REGISTER: To register an effect is to "show" it to the spectators in a
way which cannot be mistaken. It is sometimes said that an effect, a
bit of "business," or an emotion which an actor is endeavoring to
portray, "will not register," meaning that it will not be understood
by the audience in the way intended by the director. Very often a
lighting effect does not "register" as it was thought it would. Again,
an actor may wish to "register" disgust or hatred, and yet he may
convey the idea that he is portraying only fear. The word covers
various meanings. In writing your story in action (in the scenario or
continuity), if a character is hiding behind a curtain, watching an
exhibition of cowardice in another character, instead of saying "Tom
shows by his actions that he considers Jack an arrant coward,"
thereby using twelve words, you may write, "Tom registers disgust at
Jack's cowardice," which uses only six words; but do not use this
technical term too frequently in this manner.

RELEASE: Each producing company "releases" or places on the market a
certain number of films every month. Each of these films, therefore,
is termed "a release." The "release date" is the day upon which copies
of the film are given out to different exhibitors, to be shown to the
public for the first time.

SCENARIO: Correctly applied only to that part of the photoplay
manuscript which describes the development of the plot, scene by scene
and situation by situation; the complete story is swiftly _outlined_
in the synopsis, but in the scenario it is told--that is, worked
out--in action. The continuity of action; often called "the
continuity."
